my sprinkler es positiored below the Sur- .fece of the street with the sprinkler cap proecting shove seid surface and in operative s,

position. Fig. 2 is a horizontal section teken on the plane indicated by the lines 2 2 of Fig. l. Fig. 3 is a similar View taken on the lines 3 3 of Figlr Fig. 4 is a dia rhinmatic view-of e system including s p' urality of my sprinkling units.

In taking up the description; f the Asti-ue tural features of my invention I will first here particular reference to Fig. l in which one of my sprinkling units is'most clearly shown as en entirely. A

The numeral 1 designates a. water mein-of4 the usual construction located some distance below the surface of the street and provided l with the three way union 2 in the upper part of which is positioned the supply pipe 3. The mein portion of mysprinkling devioe comprises `e tired pipe 4 and a' movable pipe 5 adapted for longitudinal displacement' -within seid pipe 4. -A suitable sleeve pipe 6 internally screw threaded-as at-T'upon each extremity for portion of the`length thereof is threaded upon the lower extremity of the xed pipe 4 und' the upper er:-A tremity of the supply pipe 3 in suoli meu ner that u water tight jointis" formed.

The sliduble inner pipe is internally screw threaded as e118 for the portion-odjacent its upper extremity and externally screw threaded as shown at 9 upon its lower` sev extremity. Theinternelly screw threaded ring 1f) is threeded upoirthis lower entr-einity of the pipe 4 and is adapted to-be ernbraced by the-sleeve 6 in slidable relation` thereto, On the upper face of this ring 1.0 I provide an opstanding inverted V-shnped ex'tension 11 which is formed integrally .therewith and which is adapted to engage in a correspondingly shaped notch 12 which is formed in the lower edge of theliixcd pipe s, said notch and seid extension serving the purpose to be hereinafter clearly hro'uoht out. Suitable resilientmeans such as tlhe expendiifipr spring 13 is adapted to be posi-v tioned within the sleeve pipe 6 veuri-minding Y A' the lower extremity ofthe slidable pipe 5 and is adapted to bear upon the shoulder Atermed within the sleeve pipe 6 by the upper
